A decayed tooth can cause infection in the gums...if your gums are swollen, red and/or bleeding then you have Gingivitis. This is caused my not brushing your teeth thoroughly and flossing. Food gets trapped between the gums and teeth causing the gums to pull away from the tooth and it turns to plaque which can only be removed by your dentist. If left untreated it can also lead to tooth loss due to bone loss. I hope this helps and wish you all the best. It's tough when you need dental care and can't afford it. Good luck.
Thank you very much. I had a broken tooth on the right side of my mouth which had the same issue, and bc it hurt to chew on that side i had to eat on the left side until i was able to have it pulled. With in that time some how i was eatting a cacker which created another hole in another tooth on the left side. Well I was able to get the tooth pulled on the right side about 4 wks ago and after that the left side gave me ..... you know and now i have that oder again. Was hoping there was somthing else i could do. but thanks again i will look in to that.
Also do know if that bad tooth willl create gum issues?
The odor is being caused by the decay in the tooth and the only way to get rid of it is to have the tooth pulled. I would call some dentists and tell them your story...some will charge you much less than normal and some will allow you to pay in like 3 payments. I hope you find one that will help you and I wish you all the best.
